Little Oddities in the Star Wars Trilogy

I don't know if this is an oddity or it's supposed to be a story point. And my wife pointed it out to me.
After doing the whole mind trick on the Stormtroopers to hide the droids, why do they immediately send the same droids back outside where there are loads of Imperials milling about who might recognise them?
Either way it's massively retarded.
